[git pull] device-mapper patches for 3.0

[Alasdair G Kergon]

Please pull from:

  master.kernel.org:/pub/scm/linux/kernel/git/agk/linux-2.6-dm.git master

to get the following device-mapper patches for inclusion in 3.0.

The main enhancement this time is further integration with the md code, with
raid1 now supported.  Patches making use of this will shortly go into userspace
LVM, so it'll be possible to create Logical Volumes using the md raid
implementations.

(I had hoped to include the new thin provisioning target in this pull
request, but I'm holding it back in linux-next for now because of some
unresolved reports of data corruption.)
